A sample of glucose, C6H12O6, contains 6.02 * 1022 atoms of carbon. How many moles of hydrogen atoms and how many moles of glucose does it contain.

Because of the chemical formula of glucose we can infer the rations of each atom from one another, we can see that every 6 atoms of carbon there are 12 atoms of hydrogen. Therefore, there is twice as much hydrogen than carbon or 12.04 * 10^22 atoms or 0.2 moles of hydrogen in the sample. Following this we can infer that a glucose molecule needs 6 atoms of carbon, therefore we divide the amount of carbon by 6, and converting it into moles we will get 0.0167 moles of glucose.

Glucose has 6 number of carbon atoms, 12 atoms of oxygen and 6 atoms of oxygen

The total number of glucose atom is 24 atoms

The atom of hydrogen is twice that of carbon

that is (6.02 x10^22) x2=1.204 x10^23atoms

the number of moles of hydrogen is solved as follows

1mole = 6.02x10^23 atoms what about 1.204 x10^23=

{ (1.204x10^23) / (6.02 x10^23) }=0.2moles

The moles of glucose

1 atom of glucose = 6.02 x10^22 x4 = 2.408 x10^23 atoms

moles = { (2.48 x10^23) / (6.02 x10^23) }=0.41moles
